How to Move Header onto side of Navbar?

[gregmlb]

How do I edit the header and/or navbar templates so that my forum looks like the following:

BEFORE User Login


AFTER User Login
Same as above, but with the "Welcome User, Notifications, My Profile, Settings, and Log Out" on the navbar (in place of login/Help/Register shown above).

I have no idea exactly what to edit, how to do it, etc. I've looked at the "vB4 Skinning Your Forum in 10 Easy Steps" PDF, and also the "vB4 Forum StyleVars" PDF - but those deal with cosmetic issues (not location issues).

Is there documentation somewhere that will give me the information I need in order to successfully modify the header and navbar templates - to do what I show above? Or how do you recommend I figure out how to do this? I'm good with HTML, but bad with PHP.

The above is a work-in-progress for a 3.8.6 to 4.1.0PL2 upgrade - residing on a separate test forum. Any input anyone can give me would be greatly appreciated - thanks!!!
